LP3988  
Micropower, 150mA Ultra Low-Dropout CMOS Voltage  
Regulator With Power Good  
n 40dB PSRR at 10kHz  
General Description  
n 1 µA quiescent current when shut down  
The LP3988 is a 150mA low dropout regulator designed  
n Fast Turn-On time: 100 µs (typ.)  
specially to meet requirements of Portable battery-  
applications. The LP3988 is designed to work with a space  
saving, small 1µF ceramic capacitor. The LP3988 features  
an Error Flag output that indicates a faulty output condition.  
n 80 mV typ dropout with 150mA load  
n −40 to +125˚C junction temperature range for operation  
n 1.85V, 2.5V, 2.6V, 2.85V, 3.0V, and 3.3V  
The LP3988’s performance is optimized for battery powered  
systems to deliver low noise, extremely low dropout voltage  
and low quiescent current. Regulator ground current in-  
creases only slightly in dropout, further prolonging the bat-  
tery life.  
Features  
n 5 bump thin micro SMD package  
n SOT-23-5 package  
n Power-good flag output  
Power supply rejection is better than 60 dB at low frequen-  
cies and starts to roll off at 10 kHz. High power supply  
rejection is maintained down to lower input voltage levels  
common to battery operated circuits.  
n Logic controlled enable  
n Stable with ceramic and high quality tantalum capacitors  
n Fast turn-on  
n Thermal shutdown and short-circuit current limit  
The device is ideal for mobile phone and similar battery  
powered wireless applications. It provides up to 150 mA,  
from a 2.5V to 6V input, consuming less than 1 µA in disable  
mode and has fast turn-on time less than 200µs.  
Applications  
n CDMA cellular handsets  
n Wideband CDMA cellular handsets  
n GSM cellular handsets  
n Portable information appliances  
n Tiny 3.3V 5% to 2.85V, 150mA converter  
The LP3988 is available 5 pin SOT-23 package and 5 bump  
thin micro SMD package. Performance is specified for −40˚C  
to +125˚C temperature range and is available in 1.85, 2.5,  
2.6, 2.85, 3.0 and 3.3V output voltages.  
Key Specifications  
n 2.5 to 6.0V input range  
n 150mA guaranteed output
